Neutralizing capacity against W or D pseudovirus induced by a booster with SW-Vac 2µg formulation. BALB/c mice were immunized on Days 0 and 14 with commercial Gam-COVID-Vac-rAd26/rAd5 or AZD1222/ChAdOx1 vaccine plus a booster with SW-Vac formulation, Gam-COVID-Vac-rAd5 or AZD1222/ChAdOx1 on Day 49 delivered intramuscularly (A). Serum was collected on Day 14 after the last dose. Neutralizing titers were measured by 50% inhibition for the pseudotyped virus (CoV2pp-GFP) in immunized and non-immunized mice (B). Absolute inhibitory concentration was calculated as the corresponding point between the 0% and 100% assay controls. Fifty % inhibition was defined by the controls for all the samples on the same plate. Data is presented as the fold change of CoV2pp-GFP related to the minimum value detected in immunized animals. For statistical analysis, one-way ANOVA with Bonferroni`s multiple comparisons test was used. ****p < 0.0001.
